Abstract
The utility model discloses a tightening ring structure with circulating cooling system, which comprises a tightening ring and an external circulating pipeline of the tightening ring, wherein an inner circulating pipeline is arranged inside and along the tightening ring, the upper and the lower ports of the inner circulating pipeline respectively are an inlet and an outlet, and the inlet and the outlet of the inner circulating pipeline are communicated with the external circulating pipeline through a circulating oil pump. A set of circulating cooling system is arranged on the tightening ring, which carries out circulating oil cooling to the tightening ring and products in the tightening ring, and reduces the inner temperature to realize the aim of reducing the plucking probability of the tightening ring.
Description
Technical field
The utility model relates to the tightening ring recycle oil cooling system of all kinds of bales catch riveting progressive dies in a kind of cold stamping industry.
Background technology
Bales catch riveting progressive die is extensive use of in the silicon steel punching industry now because of its practicality characteristic efficiently.For example all kinds of electric machine rotor products are folded riveting, rectifier iron core, automotive ignition circle iron core etc. and are all adopted bales catch riveting mode to substitute manual inserted sheet or welding in the past, use manpower and material resources sparingly and efficient very high.But the easy plucking phenomenon of bales catch riveting progressive die ubiquity tightening ring influences the normal use of mould.
The utility model content
The utility model technical issues that need to address just are to overcome the defective that has the easy plucking phenomenon of bales catch riveting progressive die ubiquity tightening ring now, influences the normal use of mould, a kind of tightening ring structure that has circulating cooling system is provided, it installs a cover circulating cooling system on tightening ring, tightening ring and interior product thereof are carried out the recycle oil cooling, reduce internal temperature to reach the purpose that reduces tightening ring plucking probability.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of tightening ring structure that has circulating cooling system of the utility model, comprise tightening ring and tightening ring outer loop pipeline, in the described tightening ring, be provided with an internal recycle pipeline along tightening ring, the upper and lower port of described internal recycle pipeline is respectively import and export, and described internal recycle pipeline import and export is communicated with by oil circulating pump and outer loop pipeline.
Described outer circulation pipeline is provided with a circulating cooling medium pond.
Described circulating cooling medium is a cold oil.
The utility model is provided with an internal recycle pipeline in tightening ring inside, and at the upper and lower port of internal recycle pipeline recycle oil is set and imports and exports, ceaselessly add to the cold oil in the cooling bay in the tightening ring by oil circulating pump, reduce the tightening ring internal temperature, avoid tightening ring and interior product plucking thereof.
The utility model cooperates the purpose that realizes reducing the tightening ring internal temperature, reduces product plucking probability by oil circulating pump and cold oil.
The utility model scope of application is wider, and the folded riveting of all kinds of electric machine rotor products all can be adopted the circulation type of cooling described in the utility model, when reducing the plucking frequency, can also improve drawing velocity.Experimental data shows, folded riveting mould with the traditional structure tightening ring, about 200～250 times/minute of normal drawing velocity, and the folded riveting mould of employing the utility model recycle oil cooling structure tightening ring, towards scooter to 350～400 time/minute, and save the time of keeping in repair mounting or dismounting in a large number because of the mould plucking, can obviously improve ram efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of tightening ring structure that has circulating cooling system of the utility model, comprise tightening ring 1 and tightening ring outer loop pipeline 2, in the described tightening ring, be provided with an internal recycle pipeline 3 along tightening ring, the upper and lower port of described internal recycle pipeline is respectively import and export 4,5, and described internal recycle pipeline import and export is communicated with by oil circulating pump 6 and outer loop pipeline.
Described outer circulation pipeline is provided with a circulating cooling medium pond 7.
Described circulating cooling medium is a cold oil.
The direction of arrow is that cold oil circulates direction among Fig. 1.
The utility model is provided with an internal recycle pipeline in tightening ring inside, and at the upper and lower port of internal recycle pipeline recycle oil is set and imports and exports, ceaselessly add to the cold oil in the cooling bay in the tightening ring by oil circulating pump, reduce the tightening ring internal temperature, avoid tightening ring and interior product plucking thereof.
The utility model cooperates the purpose that realizes reducing the tightening ring internal temperature, reduces product plucking probability by oil circulating pump and cold oil.
The utility model scope of application is wider, and the folded riveting of all kinds of electric machine rotor products all can be adopted the circulation type of cooling described in the utility model, when reducing the plucking frequency, can also improve drawing velocity.Experimental data shows, folded riveting mould with the traditional structure tightening ring, about 200～250 times/minute of normal drawing velocity, and the folded riveting mould of employing the utility model recycle oil cooling structure tightening ring, towards scooter to 350～400 time/minute, and save the time of keeping in repair mounting or dismounting in a large number because of the mould plucking, can obviously improve ram efficiency.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
